Case Study: Avison Young

“ We’ve found our maintenance costs for air distribution equipment is next to nothing with UFAD compared to other buildings we have with traditional overhead systems. . . there are very few moving parts with UFAD . . . We have far less occupant complaints”.

VP Operations - Avison Young

Avison Young employs Raised Access Floors & UFAD systems in their Headquarters office whenever possible because the combination of UFAD & Raised Access Floors provide the best overall flexibility & long-term functionality for both tenant construction and operation cost management. Occupant comfort and tenant fit-out savings in time and costs make the building more marketable.
